Okay, so you know that terrifying/aggravating moment when your kid comes to you at 10:00pm on a school night and tells you he or she needs a treat for the bake sale the next morning? What, your child has never done that?!?! Bless you, sweet mama — your day is comin’…
But yeah, it’s just one more reason to pin this brownie mix cookie recipe STAT. Because when you’re armed with this great recipe, plus a box of your favorite brownie mix, you’re ready for anything that comes your way!
Ingredients For Making Brownie Cookies From Brownie Mix
Got a box of brownie mix lurking in your pantry? You can make these easy brownie cookies! Don’t have one? What kind of person even are you?! J/K, but seriously, you’re going to want to keep at least one box on hand from now until forever…
- your favorite 18-oz. brownie box mix* (mine is Ghirardelli Chocolate Supreme)
- vegetable oil (any light flavored oil: canola, coconut, avocado, etc.)
- and one or two eggs
- chocolate chips or chunks are optional, but highly recommended
It almost seems too good to be true, doesn’t it! But yeah, you only need 3 simple ingredients — four if you’re a chocoholic like myself. You might also consider picking up these tools, if you don’t already have them (they will make baking ANY cookie infinitely easier):
- parchment paper (these precut sheets are the BEST!)
- a medium cookie scoop (ideal for portioning out your cookies)
- a spoonula spatula (my fave for combining ingredients together)
PRO TIP: This brownie mix cookie recipe is ideal for kids that are beginner bakers! Make the process even more fun with a set of these adorable mini utensils. They’re the perfect size for small hands and just so stinking cute!! I *may* have just picked up a set for myself…
Okay, are you ready to make some brownie mix cookies now? Let’s do this!!
How To Make Cookies From Brownie Mix
Honestly, now that I’m getting ready to tell you how to make this brownie cookies recipe, I’m wondering if I should even call this a recipe, LOL. It pretty much goes like this:
- Dump the boxed brownie mix into a large bowl. In the case of the Ghirardelli Chocolate Supreme box brownie mix that I used, it comes with a packet of chocolate syrup. Go ahead and squeeze that in, as well. (By the way, Ghirardelli has absolutely NO idea who I am. I just happen to love, LOVE their brownie mixes!)
- Add 1/2 cup of your preferred vegetable oil. If you’re curious, I happen to use avocado oil for just about all of my cooking and baking, but any light flavored oil will work here. Or you can use butter — see the recipe card notes for this swap!
- Add one large egg — OR one large egg + one egg yolk (more on this in a moment).
- Now stir, stir, and stir some more. The brownie mix cookie batter is VERY thick, so you will need to do a lot of scraping to mix it all together. Which is why I adore this spoonula spatula! You can also use a hand mixer for this step, if you prefer.
- Chocolate lovers, if you’re adding chocolate chips or chunks, go ahead and fold them in now. I used the Private Selection 62% Cacao Dark Chocolate Chunks from Kroger, and they are SO good! Plus the square shape makes these simple & easy cookies made with brownie mix look a little more upscale.
Brownie Cookies Made With One Egg Or Two?
Okay, so it’s really one egg OR one egg plus one egg yolk, and the deciding factor is pretty much how ooey-gooey you want your brownie mix cookies recipe to turn out…
Think about what you typically reach for when faced with a freshly baked pan of brownies. Do you go for one of the outer squares with the crispy, chewy edges or choose the fudgy brownie texture of a center square? You can totally customize this brownie cookie recipe from a box to suit either choice.
Are you a chewy edges kind of brownie lover? Stick with one large egg for a crispier brownie cookie. But if you’re one of those brownie lovers that always reaches for a soft fudgy center brownie piece, add one large egg plus one egg yolk for a chewier cookie.
Tips For The Best Chocolate Brownie Cookies
So here’s the thing… Even though we’re making boxed brownie mix cookies, it doesn’t mean that we don’t want them to look bougie and beautiful, you know like they’re totally NOT from a mix.
Am I right? Well, it just so happens I have a few parting tips that make ALL the difference in turning out the best brownie mix cookies.
- Use a medium cookie scoop to portion out the brownie batter dough. This will not only ensure that all of your cookies are the same shape and size, but it’s also the size that I tested for the bake time listed in the recipe. This size scoop equals 1.5 tablespoons, so in a pinch, that’s how many tablespoons of dough you should use per cookie. Also, these rich cookies spread quite a bit, so I recommend only portioning out 8 to a baking sheet.
- Line your cookie sheet with parchment paper or a silicone baking mat. These cookies are fairly delicate and will stick to the pan otherwise.
- Add a little bit of extra chocolate chips or chunks for prettier cookies. This tip works for any and every kind of cookie that contains baking chips or mix-ins! Press 2-3 chips/chunks into each dough ball after portioning them out with the scoop. The “extras” will stay on the top of the cookie while it’s baking, making for a perfect cookie that looks extra luscious. Peanut butter chips or white chocolate chips would be a delicious addition, as well!
- Don’t over bake your cookies! These brownie mix cookies can quickly go from perfect to over baked, so it’s important to use visual cues as much as baking time. My cookies were perfectly cooked at 10 minutes in a 350 degree oven, but I would recommend starting to check them around the 9-minute mark. They’re done when they’re no longer shiny on top, even though they may still look slightly underbaked overall.
- Don’t try to transfer these cookies to a cooling rack immediately. Let the cookies cool for 5 minutes on the baking sheet, and then you can safely move them to a wire rack.
Have I convinced you to try this ridiculously easy brownie cookie recipe, yet?
Just to quickly recap: it’s just 3 ingredients (4 if you add chocolate chips), 5 minutes to mix up and portion out, and 10 minutes to bake. And the best thing is these delicious cookies are cool enough to eat in just about 5 more minutes!
I mean, who wants to wait 45 minutes for a classic brownie recipe to bake and then another 45 minutes to an hour for the pan of brownies to cool? NOT ME!
After a little research, I discovered that Duncan Hines changed the formulation for this variety roughly 9 months ago. And boy, do bakers have STRONG opinions about the change!! So I’m going to assume that the reported issues are a result of this new formula and recommend that you steer clear of it for now.

Made these using a Betty Crocker dark chocolate mix using 1 stick of melted butter. Baked for 12 minutes, came out chewy and delicious.

These came out great for me and our family loved them! Not all brownie mixes are 18oz. There are quite a few varieties that are less and some have a little more. Not sure if that would have been the case for those whose cookies didn’t turn out, but something to keep in mind.

I just made these and they are delicious. I made the butter method with 1 egg and 1 yolk. Let the batter rest 15 minutes and baked for 13 minutes. They are chewy on the edges and gooey in the middle. Perfection!!

I followed this recipe to the T. All my ingredients were new and in date. This by far was the Worst recipe I’ve ever made. The dough was crumbley and did not spread as described. Needless to say, I was very disappointed and ended up wasting the ingredients due to this “Cluster F—-.” Don’t waste your time or ingredients on this. Absolutely do not recommend!

@Tara Kuczykowski, Mine did the same thing. Fudge variety of Duncan Hines.

I'm sorry it didn't turn out well for you, Gloria. Could you let me know what brand of brownie mix you used? I've tried several and never had the issue you described, so I'd like to see if I can figure out what went wrong.
